Sync Source Selection

A 3-position toggle switch for selecting the audio sync source. The switch’s ‘down’ position is latching, while its ‘up’ position is momentary. Repeated ‘upward’ presses on the switch scroll through the possible external sync sources. The

adjacent amber LEDs indicate the currently-selected source.

When the LED for the desired source is on, the switch may be placed in the latching ‘down’ position to prevent inadvertent further changes of sync source.

Front Panel Description

PSU Status

Two bi-colour LEDs confirming the current status of each PSU. The LEDs are green in normal operation and flash red if a PSU fault condition is detected.

SDI Lock LEDs

Four tri-colour LEDs, for SDI inputs 1 to 4. Each illuminates when a valid SDI video signal is detected at its input, and the colour indicates the interface standard in use.

Colour	SDI Format
Yellow	SD-SDI
Green	HD-SDI
Red	3G-SDI
Off	No Valid SDI Signal Detected

SRC Control

Four 2-position toggle switches controlling the four 16-channel output SRCs. The switch also enables external GPI control of each SRC.
